We show that perceived size of visual stimuli can be altered by matches between the contents of visual short-term memory and stimuli in the scene. Observers were presented with a colour cue (to hold in working memory or to merely identify) and subsequently had to indicate which of the two different-coloured objects presented simultaneously on the screen appeared bigger (or smaller). One of the two objects for size judgements had the same colour as the cue (matching stimulus) and the other did not (mismatching stimulus). Perceived object size was decreased by the reappearance of the recently seen cue, as there were more size judgement errors on trials where the matching stimulus was physically bigger (relative to the mismatching stimulus) than on trials where the matching stimulus was physically smaller. The effect occurred regardless of whether the visual cue was actively maintained in working memory or was merely identified. The effect was unlikely generated by the allocation of attention, because shifting attention to a visual stimulus actually increased its perceived size. The findings suggest that visual short-term memory, whether explicit or implicit, can decrease the perceived size of subsequent visual stimuli. 相似文献

ABSTRACT This research was designed to test the hypothesis that motor practice can enhance the capabilities of motor control in healthy controls (NC) and patients with a diagnosis of probable Alzheimer's disease (AD) and mild cognitive impairment (MCI), and consequently results in better motor performance. Approximately half of the subjects in the NC (n = 31), AD (n = 28), and MCI (n = 29) either received or did not receive practice on a task of fast and accurate arm movement with a digitizer. Changes in movement time (MT), movement smoothness (jerk), and percentage of primary submovement (PPS) were recorded and compared among the three groups across six blocks of trials (baseline and five training sessions). For all subjects, practice improved motor functions as reflected by faster and smoother motor execution, as well as a greater proportion of programming control. Compared to unaffected matched controls, AD and MCI subjects exhibited a greater reduction in movement jerk due to practice. Movement time and PPS data revealed that motor practice appeared to reduce the use of “on-line” correction adopted by the AD or MCI patients while performing the aiming movements. Evidently, their arm movements were quicker, smoother, and temporally more consistent than their untrained peers. The findings of this study shed light on how MCI and AD may affect motor control mechanisms, and suggest possible therapeutic interventions aimed at improving motor functioning in these impaired individuals. 相似文献

This article applies a two-process “neural autopilot” model to field data. The autopilot model hypothesizes that habitual choice occurs when the reward from a behavior has low numerical “doubt” (i.e., reward prediction errors are small). The model toggles between repeating a previous choice (habit) when doubt is low and making a goal-directed choice when doubt is high. The model has ingredients established in animal learning and cognitive neuroscience and is simple enough to make nonobvious predictions. In two empirical applications, we fit the model to field data on purchases of canned tuna and posting on the Chinese social media site Weibo. This style of modeling is called “structural” because there is a theoretical model of how different variables influence choices by agents (the “structure”), which tightly restricts how hidden variables lead to observed choices. There is empirical support for the model, more strongly for tuna purchases than for Weibo posting, relative to a baseline “reduced-form” model in which current choices are correlated with past choices without a mechanistic (structural) explanation. An interesting set of predictions can also be derived about how consumers react to different kinds of changes in prices and qualities of goods (this is called “counterfactual analysis”). 相似文献

厌腻感是指消费者对连续或过量消费同一产品或服务的效用感、享乐感或满意度下降, 负面感知逐步抑制正面感知的主观情绪体验。为缓解或防止厌腻感的产生, 消费者会采取品牌转换、多样化寻求、控制消费周期等行为, 因此厌腻感已成为企业或店铺培养顾客忠诚的主要障碍。国外文献分别从厌腻感的生成过程、功能反应、知觉状态和属性感知等方面, 划分厌腻类型; 剖析了厌腻感生成的享乐适应、边际效用递减、认知失调以及最佳刺激水平等理论原理及机理; 探讨了生理厌腻感和心理厌腻感生成的诱发因素及影响效应; 验证了外部因素和个体因素的调节作用; 同时探讨了消费者缓解或防止厌腻感的主要策略及行为反应。最后对现有文献的研究思路、特点和不足进行了评述, 提出了未来研究方向。 相似文献

采用三角验证法对长春180名10.1-15.3岁儿童进行研究,以自然范畴的事物、家庭内外事件和熟悉的文本为测验材料,探测了儿童对图式特征的认知特点。结果发现:(1)儿童对自然范畴、事件、文本图式特征的认知存在三级水平:①成分水平,②成分与整体水平,③整体水平。这三级水平与儿童思维特点相一致并受生活经验或事件的制约。(2)儿童对三类图式特征认知是随年龄的升高而不断提升的,其标志是对图式本质的理解、概括与把握不断加深,到13岁以后儿童对三类图式特征的认知发展迅速。 相似文献

中学生厌学心理及其干预与学习效率的相关研究 总被引:17,自引:1,他引:16
本研究旨在考察两个问题:1.心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2.厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明:心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。 相似文献

The present study was designed to compare the psychological well-being of mothers of children with mental retardation in the USA and Korea. The Double ABCX model of stress proposed by McCubbin and Patterson (1983) was evaluated for the two national groups. Thirty-eight American and 40 Korean mothers participated in the home-visit interview. The path models in the present study partially supported the ABCX model, but different path models for the two national groups provided important explanations for the well-being of mothers from the two nations. The cause of stress for the American mothers was specific to the individual variables. For Korean mothers, cultural values that carry social influence were more strongly associated with their attitudes towards the child and their experience of stress. 相似文献

选择性注意加工机制上学困生和学优生的比较研究 总被引:14,自引:3,他引:11
本实验使用正、负启动技术 ,在严格控制各种条件下比较学困生和学优生在选择性注意加工机制———目标激活和分心物抑制方面的差异 ,进而探讨学困生在选择性注意加工机制上所存在的问题。结果显示 ,学困生和学优生的正启动量差异不显著 (p >0 .0 5 ) ,但学困生的负启动量显著小于学优生 (p <0 .0 0 1。这一结果说明 ,学困生在对目标反应期间易受分心物干扰 ,其抑制分心物干扰的能力较弱。同时启示我们应注重训练学困生抑制分心物干扰的能力 相似文献
